title: On the possible benefits of a hybrid VMAT technique in the treatment of non-small cell lung cancer.
abstract: To assess, using clinical cases, the potential of a hybrid technique for the treatment of non-small cell lung cancer (NSCLC)-blending volumetric-modulated arc therapy (VMAT) and conformal radiation therapy (CRT) fields, and to consider potential issues with implementation of such a technique. Eight clinical cases already treated with CRT were used for a planning study comparing target coverage and organs at risk (OAR) sparing between CRT and hybrid VMAT (VMATh). Quality assurance (QA) implications of the resultant hybrid plans are discussed. The hybrid technique resulted in superior target conformity or improved sparing of OAR or both. The hybrid technique shows promise, but the QA implications of motion at treatment need careful consideration.
